Definitions

  • a radial distance of the transformer center of mass of each of the transformers from the longitudinal axis of the tower may amount to between 1.0 and 1.8 for example of the tower radius.
  • Other transform ers of the plural transformers may be arranged outside the annular region.
  • the two transformers have similar, in particular same, construction and/or shape and/or type and are arranged within the nacelle substantially mirror symmetrically to a vertical plane lying in a rotation axis of a rotation shaft at which plural rotor blades are mounted.
  • the back portion of the of the nacelle may be a region oppo site to a front portion of the nacelle, at which the nacelle may comprise a hub connected to the rotation shaft, wherein at the hub plural rotor blades may be connected.
  • the front portion of the nacelle may face the wind.
  • the two symmetrically arranged transformers may be arranged at the two sides of the rotation shaft. According to embodiments, however, at least one trans former of the plural transformers may not have a symmetrical ly arranged counterpart.
  • This transformer (also referred to as a third transformer) may also be arranged close to a lon gitudinal axis of the tower but in the back portion of the nacelle.
  • the back portion may be arranged overlapping or be low an imagined (e.g. axial) extension of the rotor shaft backwards .
  • Fig. 1 schematically illustrates an elevational longitudinal cross-sectional view of a nacelle of a wind turbine according to an embodiment of the present invention
  • Fig. 4 schematically illustrates an electrical diagram of a wind turbine according to an embodiment of the present inven tion
  • Fig. 2 omits details and in particular does not illustrate all elements in detail described with reference to Fig. 1 which are arranged within the nacelle 223.
  • Fig. 2 illustrates in the side view a second transformer 203 which may be simi larly configured as the second transformer 103 illustrated in Fig. 1.
  • the magnetic core 671 comprises further a first con nector core 677 connecting first ends of all magnetic core legs 673A, 673B, 673C and further comprises a second connect or core 679 connecting second ends of all magnetic core legs 673A, 673B, 673C.
  • a casing 681 encloses the magnetic core 671 and all primary coils 655A, 655B, 655C and all secondary coils 657A, 657B, 657C.
